Sling Siege

Drag back from the sling, let go, and knock the tower down. You get three birds per level — run out and the tower is rebuilt and the attempt is counted. Every level is a pure function of the seed, so the Daily is the same tower for the whole room, and any seed can be played again exactly.

Drag anywhere on the field to pull the sling back, and release to fire. On a keyboard: ↑ ↓ set the pull length, ← → set the angle, and Space fires.
